The project is aimed to design a system using which we can send the messages to the mobile by using PC and a GSM modem, without internet connection to the PC. GSM Modem can accept any GSM network operator SIM card and act just like a mobile phone with its own unique phone number. Advantage of using this modem will be that you can use its RS232 port to communicate and develop embedded applications. Applications like SMS Control, data transfer, remote control and logging can be developed easily. The modem can either be connected to PC serial port directly or to any microcontroller. The project is designed in such a way that the controller will be interfaced to the PC, as well as to the GSM modem through a line driver IC max232 for serial communication. Serial communication is often used either to control or to receive data from an embedded microprocessor. Serial communication is a form of I/O in which the bits of a byte being transferred appear one after the other in a timed sequence on a single wire. The front end application will be developed on C# .NET platform for the visual effects so that the application can be easily accessed. The application will be designed in such a way that it contains a text box in which we can enter the required text and as the application always interact with the serial port it sends that text to the PC serially and then the controller sends it to the GSM modem in an SMS format as per the code logic. So that the mobile with the preprogrammed number will receive that particular message through GSM modem. This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac output of secondary of 230/12V step down transformer.

According to ancient Greek scripts BIOMETRICS means study of life. Biometrics studies commonly include fingerprint, face, iris, voice, signature and hand geometry recognition and verification. Many other modalities are in various stages of development and assessment. Among these available biometric traits Finger Print proves to be one of the best traits providing good mismatch ratio and also reliable. Registering the attendances of students has become a hectic task as sometimes their attendance may be registered or missed. To overcome this problem i.e. to get the attendances registered perfectly, we are taking the help of two different technologies viz. EMBEDDED SYSTEMS and BIOMETRICS. Firstly discussing about Biometrics we are concentrating on Fingerprint scanning. For this we are using FIM 3030N high voltage module as a scanner. This module has in-built ROM, DSP and RAM. In this we can store the fingerprints of up to 100 users. This module can operate in 2 modes i.e., Master mode and User mode. We will be using Master mode to register the fingerprints which will be stored in the ROM present on the scanner with a unique id. The fingerprint module will be interfaced with the microcontroller through serial interface. The images of the students of a particular class will be scanned and stored in the microcontroller. The students have to scan their images to register their attendance daily. When the student has to register his attendance on that particular day, he has to scan his fingerprint image. The fingerprint module scans the student’s image and passes the scanned image to the microcontroller. The controller reads the scanned image, compares this image with the already stored image. If both are matched, the student’s attendance will be registered for that day. If it is not matched, the student’s attendance will be marked as absent and buzzer indication will be given. By simply pressing a switch, we can get the list of absentees for that day. We can see details on 16X2 LCD. (In this project we can connect microcontroller to PC and PC maintain presents and absents list with help of C# application-But it is optional).
